WCB-body gate valve with graphite packing and a published GOST drilling reference.
The cast-steel gate-valve listing identifies WCB for the body and bonnet, with soft-graphite packing and a graphite-steel gasket. Rui Mai publishes DN50–600 and PN16 for this handwheel-operated range. Its introductory temperature entry spans −46 to 400°C; the actual material qualification and pressure-temperature limits should be confirmed for the ordered configuration.
